What it is

The Johnson & Starley 1000-0019015 is a pressure relief valve for the Reno range of gas boilers. It opens to discharge water when system pressure exceeds the valve's set limit, protecting the boiler and heating circuit from over-pressurisation. It is supplied complete with nut, olive and pipe.

Signs this part needs replacing

  • Water continually dripping or running from the pressure relief discharge pipe
  • System pressure rising above the normal cold-fill reading and not settling
  • The valve weeping at the body or outlet when the system is at normal pressure
  • Discharge pipe permanently wet or stained, even with the boiler cold
  • Pressure gauge fluctuating as the valve opens and reseats repeatedly

Before you order

  • Confirm the boiler model and, where known, the GC number against the fitment list
  • Check the existing valve's connection arrangement and whether the nut, olive and pipe are required
  • Verify the discharge pipework is correctly routed and able to take the replacement valve outlet
